These barrels work well on both Bb and A clarinets. Many musicians are able to use the same barrel on both instruments, with or without tuning rings - an extra perk for the orchestral musician.
Generally, choose the same length barrel that you are currently using on your set-up. If you are very sharp and tend to pull the barrel out more than a millimeter, consider a longer barrel or purchasing tuning rings.
Barrels fit most brands of clarinets with standard tenon diameters (Buffet, Yamaha, etc). There are exceptions for instruments with non-standard tenon diameters. Please feel free to send us an email if you are unsure about the compatibility of your clarinet.
NOTE: Due to the length of the wood aging process and demand for certain sizes, there may be short periods of time where some barrels are not in stock. Please check back frequently for updates on any products not in stock.
